When you load this page and have the Toolbar Browser installed, the Alexa toolbar will automatically appear. Please note that you need to click the SAVE button next to the Toolbar name to add it to your toolbar.
The Alexa Rank features transmit the URL information to Alexa in order to retrieve the ranking data. URL parameters are not stripped as that is the default Alexa Toolbar behaviour. For additional privacy, you can replace the $URL variable with $STATICURL in the code as $STATICURL does not send parameter data.
